Volkswagen Golf Service & Repair Manual: Draining refrigerant circuit using air conditioner service station
WARNING
| High-voltage on high-voltage system. Danger of
electric shock on air conditioner compressor! |
| Models with a high-voltage system: now de-energise
the high-voltage system
→ Electric drive; Rep. gr.93. |
|
| Depending on the type of equipment chosen, there may be
variations in the required procedure (always follow user's
manual for the equipment being used). |
| The refrigerant circuit must be discharged if parts of the
refrigerant circuit must be removed, if there is uncertainty
about the quantity of refrigerant in the circuit or if safety
measures require it. |
| All important operating instructions associated with the air
conditioner service station for working with refrigerants can be
found in the air conditioner service station operator's manual. |
| – |
Connect air conditioner service station to service
connections as described in the user's manual for the vehicle
→ Rep. gr.87 and bring into operation. |
 Note
| The possibility cannot be excluded that, along with the
refrigerant, refrigerant oil is extracted from the refrigerant
circuit. In order to ensure the lubrication of the air
conditioner compressor, the refrigerant oil quantity should be
topped up with fresh oil
→ Rep. gr.87. |
| On vehicles with air conditioner compressor and no magnetic
coupling (with air conditioner compressor regulating valve
-N280-) the engine should only run for < 10 minutes with empty
refrigerant circuit and closed refrigerant circuit (the air
conditioner compressor runs with it continually). The engine
speed must not exceed 2000 rpm. |
| On vehicles with air conditioner compressor and magnetic
coupling, the engine may be started as the air conditioning
system pressure switch -F129- or high-pressure sender -G65-
(checks whether refrigerant is in the circuit) switches off the
magnetic coupling as soon as there is no refrigerant in the
refrigerant circuit. |
